HI770 microcomputer silicon dioxide analyzer photometric colorimeter

Silicon dioxide [SiO2] exists in natural water bodies that dissolve minerals. But in industrial applications, the presence of silicon dioxide is not desirable because silicon dioxide [SiO2] can cause scaling.

Product Overview

Measurement range: 0 to 200 ppm (mg/L) SiO2

Adopting innovative optical system design, with good accuracy, repeatability, and measurement time required, the carefully designed CAL Check ™ The function allows for performance validation and calibration of instruments using NIST traceable standards, with built-in reaction timers to ensure consistency between sample measurements and user results, battery status indicator lights, and automatic shutdown settings

Performance characteristics

Silicon dioxide [SiO2] exists in natural water bodies that dissolve minerals. But in industrial applications, the presence of silicon dioxide is not desirable because silicon dioxide [SiO2] can cause scaling.

Especially in high-pressure pipelines, they are more susceptible to the influence of silicon dioxide [SiO2].

It is also necessary to monitor silicon dioxide (SiO2) in heating systems and reverse osmosis factories.

The silicon dioxide [HR] photometric colorimeter has a well-known combination optical system of narrowband interference filter and silicon photodetector, ensuring accurate measurement readings every time;

Carefully designed CAL Check ™ The HI770-11 silicon dioxide [HR] NIST traceable calibration group is used to verify the performance status of the silicon dioxide [HR] photometric colorimeter.

The dedicated colorimetric cup locking design ensures that the colorimetric cup is inserted into the same position in the measuring unit each time to maintain a consistent path length for accurate results,

It is simple and convenient to add reagents to the water sample to be tested. The reagents will react with silicon dioxide [HR] in the water sample to be tested. Based on the color change after the reaction between the reagents and the water sample, the concentration value of silicon dioxide [HR] can be determined using a silicon dioxide [HR] spectrophotometer.

Built in timer - ensures that the tested water sample and silica [HR] reagent react according to the internally set standard time. At the end of the timer, the instrument will automatically read the reading, ensuring consistency in reaction time across multiple batches of measurements.

Error messages - warning issues on the display screen, including unlimited, out of range, and under range readings, as well as light source errors;

Automatic shutdown - automatically shuts down after 10 minutes of inactivity;
